To al'l'whom'it may concern.'

Be it known that I, CHARLES GROHMAN, a citizen of the United States, and a resident of Carteret, in the county of Middlesex and State of New Jersey,'have invented a new and'Improved Packing -'Tool, of which the followingis a full, clear, and exact description. v.

This invention relates to certain improvements in tools for use in applying the packing around the ends of the tubes of condensers or other similar apparatus in which packing glands are employed. 4

More particularly, the invention relates to means for applying a packing formed of a cord and' for firmly and securely forcing the paclking into place with a single blow of the too The object of the invention is to rovidev improved means for holding the endp of the cord while it isbeing wound around the mandrel, and to provide improved means for driving the packing into place.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and invwhich Figure 1 is a side'elevation of artool con structed in' accordance with my invention, a portion thereof being shown in central longitudinal section; Fig. 2 is a'longitudinal sec-,j tion through a portion of the tool on an enlarged scale, showing the parts in the position they occupy as the packing is -driven' into place; and F ig. 3 is a longitudinal section through the lower end of the mandrel, showing the means for holding the. end of the core while the latter is being woundyaround the mandrel.

In my improved packing tool, I ein loy a mandrel preferably in the form of a ollow tube 10, and of an external diameter approximately, if not exactly, the same'as the external diameter of the condenser tube A or other tube around which the packing is to be applied. The mandrel tube .preferably carries a plug 11 at the-lower end thereof, adapted for insertion within the condenser tube to center the mandrel, and also serving as a guide for a small rod 12, extending longitudinally of the tool. Within the mandrel and adjacent the lower end thereof, there is inserted a block or collar 13, held against longitudinal movement in any suitable manner and serving also as a guidefor the rod 12.V

Adjacent the lower end of the mandrel,y a narrow slot 14 is` formed, extending a short distancev` longitudinally of the tube, 4and Within the mandrelfis a needle 15, one end of which is rigidly secured in the block or collar 13 andthe other end terminates adjacent the slot 14.- The rod 12 is longitudinally movable an-d carries a block or collar 16, presenting a cam surface adapted to engage with the needle 15 adjacent the slot. The block or collar 16 normally lies adjacent the inner end of the block 11 and limits the outward movement of the rod. At the opposite end of the tool, the tube or mandrel 10 carries a handle 17 and within the tube or mandrel is a coil spring 18 engaging with the inner surface of the handle and with a iiange 19 on a cap 20, inclosing the end of the rod 12. Slidably mounted on the mandrel is a driving sleeve 21, formed of a metal having a thickness substantially equal to the thickness of the cord which is to be used as the packing, and encircling the driving sleeve is an inclosing sleeve 22. Intermediate the handle 17 and the driving sleeve 2l, is a heavy metal handle 23, longitudinally movableon the tube and forming hammer. l

In ,the operation of my improved packing tool, the rod 1'2 is forced inward against lthe action of thespring- 18, until the cam surface of the blockl enga es the needle and forces the end thereof out t rough the slot la to the position indicated in Fig. 3. cord is then slipped beneath the end ofthe needle andthe rod 12 permitted to return, so

Ythat the needle firmly engages with the Iend of the cord and holds it in place.` The re-v mainder` of the cord is 'Wound around the mandrel as indicated in Fig. 1, and the driving sleeve 2.1 is moved down the mandrel until the y'end of said sleeve engages with the end of the coil of cord. T he inclosing sleeve is then slipped'down over the cord, and the plug 11 is inserted in the end of the tube surrounding which it is desired to' place the packing. The sleeve 22 is moved down into engagement with -the surface of the tube sheet B or other late or bodyholding the tube, and the weigllit or hammer 23 is moved to the position indicated in l. By moving the ammer rapidly downwardinto engagement with theendvof the driving sleeve 21, the packing is forced into lace at a single blow, Without any danger olpbreakingthe cord or cutting it on the threads in the opening which receives the packing.

The 'downward move- The end of the ing the same in alinement witha tube, a hanydle at theopposite end of sald mandrel, a driving sleeve slidably mounted on said manyably securing ment of the cord slips it out from under the end of the needle, and the latter automatically returns to the position indicated in Fig. 2.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A packing tool, comprising a mandrel having means at one end thereof for center- `tube forming a mandrel an drel out of engagement drel for engagement with the end ofthe packing, an inclosing sleeve slidably mounted on said driving sleeve for engagement with the l outer surface of the packing, and a hammer slidably mounted on the mandrel for engagement with the driving sleeve to force the packing into position.

2. A packing tool, comprising a mandrel for the packing material, means for detachone end of the packing cord I thereto to facilitate the winding of the cord about said mandrel, and a driving sleeve slidably'mounted on the mandrel, the operation of the latter serving to detach the cord from said mandrel.

3. A packing tool, comprising-a mandrel lhaving an opemng 1n the side thereof, means within said mandrel and adapted to extend through said opening, for engagement with one end of a packing cord to hold the same in position while said cord is being wound about the mandrel, and means for forcing said packl ing gagement with said fastening means.

4. A packing tool, com rising a hollow one side thereof, a needle within said tube and terminating adjacent said slot, means for forcing said needle outward through said slot, whereinit may serve to retain in posi- Ition the end of the acking cord while the latter is being wound) about the mandrel, and means for forcing said packing off of said manwith said needle.

5. A packing tool, comprising a vhollow tube forming a mandrel and having a slot in one side thereof, a needle within said tube and terminating adjacent said slot, means movable longitudinally of said tube for engagement with said needle'to force the latter outward through said slot, whereby the end the packing into position.
